TWI807175B - Anti-pinch window and anti-pinch method - Google Patents

Abstract

An anti-pinch window and an anti-pinch method are provided. The anti-pinch window mainly includes a door panel, a glass window, a sound position detection module, and a control module. When one end of the glass window moves toward an abutting edge of the door panel to close and a sound is detected from a position close to the end of the glass window, the control module controls the glass window to stop closing. The sound detected from the surface of the glass window serves as a main-criterion for anti-pinch so that the accuracy can be improved and will not be influenced by the environment outside the care, lowering the possibility of misjudging.

Description

Anti-trap window and window anti-pinch method

The invention relates to an anti-pinch vehicle window and a method for preventing a vehicle window from being clamped, in particular to an anti-pinch vehicle window and a method for preventing a vehicle window from being clamped using sound detection.

Today's vehicles mostly use electronic switches to control the opening and closing of the windows. However, if the switch is accidentally touched by mistake, accidents may occur that the windows will pinch the user.

For example, Chinese Patent Publication No. CN 104806116 A provides an intelligent anti-pinching method and device for car windows, which mainly adopts an automatic optimization control system, monitors obstacles through infrared sensors, and transmits signals to the main control template to control the closing of car windows through the data processing module, so as to reduce car window pinching accidents.

The aforementioned patent only uses infrared rays to determine whether the user in the car is approaching the window. If it is detected that the user is approaching the window, the command to close the window will be stopped first. However, if there is an approaching object outside the window, there may be a misjudgment.

Therefore, in order to improve the accuracy of judgment, the present inventor proposes an anti-pinch window, which includes: a door panel with a window, and the door panel has an abutment adjacent to the window; a glass window is arranged on the door panel, and the glass window has an end corresponding to the abutment, and the window is opened and closed through the end against the abutment or away from the abutment; a sound position detection module is arranged on the glass window. The detection module is used to detect a sound position on the glass window; and a control module, the signal is connected to the sound position detection module, and the signal of the control module controls the glass window; when the glass window is closing and the end of the glass window moves toward the abutting edge, if the sound position is close to the end, the control module controls the glass window to stop closing.

Wherein, the sound position close to the end means that the sound position is within 15 cm from the end.

Further, a prompt module signal is connected to the control module; when the glass window is closing and the end of the glass window moves toward the abutting edge, if the sound position is far away from the end, the control module controls the prompt module to send a prompt message, and the glass window continues to close.

There is a touch sensing module signal connected to the control module. The touch sensing module includes a plurality of sensing electrode points and a transparent conductive film. The sensing electrode points are respectively arranged at the four corners of the glass window. The transparent conductive film is combined with the glass window. When a charged human body touches the touch sensing module, the touch sensing module will be triggered. The glass window stops closing, and if the sound position is away from the end and the contact sensing module is triggered, the glass window continues to close.

Further, an infrared sensing module signal is connected to the control module, and the infrared sensing module is set adjacent to the glass window; when the glass window is closing and the end of the glass window is moved toward the abutting edge, if the sound position is close to the end and the infrared sensing module is triggered, the control module controls the glass window to stop closing.

The inventor further provides a vehicle window anti-pinch method, including: a sound position detection module detects a sound position of a sound on a glass window; and when the glass window is closing, making the glass When one end of the window moves toward one of the abutting edges of a door panel, if the sound position is close to the end, a control module controls the glass window to stop closing.

Wherein, the sound position close to the end means that the sound position is within 15 cm from the end.

Further, when the glass window is being closed and the end of the glass window is moved toward the abutting edge, if the sound position is away from the end, the control module controls a prompt module to send a prompt message, and the glass window continues to close.

Further, a touch sensing module is triggered when a charged human body touches the touch sensing module. When the glass window is closing and the end of the glass window moves toward the abutting edge, if the sound is close to the end and the contact sensing module is triggered, the control module controls the glass window to stop closing. If the sound is far away from the end and the touch sensing module is triggered, the glass window continues to close.

Further, when the glass window is closing and the end of the glass window is moved toward the abutting edge, if the sound position is close to the end and an infrared sensing module is triggered, the control module controls the glass window to stop closing.

According to the above-mentioned technical features, the following effects can be achieved:

1. Use the sound on the surface of the glass window as the main criterion for judging the anti-pinch window, which can improve the accuracy, is not easily affected by the external environment of the car, and reduces the possibility of misjudgment.

2. With the sound position detection module, when the glass window is closing, if a user puts his hand on the end of the glass window, the control module can immediately stop the closing of the glass window to prevent the user from being pinched by the glass window.

3. When the user puts his hand away from the end of the glass window, the prompt module will send out a prompt message to attract other users' attention.

4. In addition to the sound position detection module, it can also be equipped with a contact sensing module and/or an infrared sensing module to further improve the accuracy and avoid misjudgment by a single sensing method.

Based on the above technical features, the main functions of the anti-pinch window and the anti-pinch method of the vehicle window of the present invention will be clearly presented in the following embodiments.

Please refer to the first and second figures, which disclose the anti-pinch window of the embodiment of the present invention. The anti-pinch window is set on a vehicle, and the anti-pinch window includes: a door panel (1), a glass window (2), and a control module (3), a sound position detection module (4), a contact sensing module (5), an infrared sensing module (6) and a prompting module (7).

This car door panel (1) has a window (11) and an abutting edge (12) [this window (11) please match the fourth figure], and this abutting edge (12) is adjacent to this window (11).

The glass window (2) is arranged on the car door panel (1), and the glass window (2) has an end (21) corresponding to the abutment (12), through which the end (21) is against the abutment (12) or away from the abutment (12) to open and close the window (11).

The control module (3) can be combined with the trip computer of the vehicle, or connected with the trip computer in a wired or wireless manner. The control module (3) is signal-connected to the sound position detection module (4), the contact sensing module (5), the infrared sensing module (6) and the prompt module (7).

The sound position detection module (4) is arranged at the four corners of the glass window (2). The sound position detection module (4) can be a sound capture device, which captures the sound on the glass window (2) to detect a sound position of a sound on the glass window (2).

The touch sensing module (5) can be of projected capacitive type. With the sensing electrode points arranged at the four corners of the glass window (2) and the transparent conductive film (Indium Tin Oxide, ITO) combined with the glass window (2), when a charged human body touches the touch sensing module (5), the capacitance of the ITO layer will change, generating an induced current, and the contact coordinates are detected by the induced current. However, the detailed structure is not drawn in the drawings, and only the sensing electrode points at the corners of the glass window (2) are used to indicate the contact sensing module (5).

An infrared emitting end (61) and an infrared receiving end (62) of the infrared sensing module (6) can be arranged on the car door panel (1) above and below the glass window (2) respectively, or on the left and right side of the car door panel (1), so that the infrared beam from the infrared emitting end (61) to the infrared receiving end (62) can cover the glass window (2) area.

The prompting module (7) can send out a prompting message by means of sound, image or light. In the embodiment of the present invention, the prompting module (7) is combined with a horn of the vehicle.

Please refer to the third figure to the fifth figure, the anti-trap window can be used to implement a window anti-trap method. When the glass window (2) is being closed and the end portion (21) is moved toward the abutting edge (12), the anti-pinch method for the vehicle window can deal with a situation where a user (A) approaches the glass window (2). Firstly, the situation where the user (A) touches the glass window (2) near the end portion (21) is described.

Please refer to the third, fifth and sixth figures, when the user (A) touches the glass window (2) near the end (21), the sound will be emitted on the glass window (2), so that the sound position detection module (4) detects that the sound position of the sound is close to the end (21). The hand can also block part of the infrared light beam, so that the infrared induction module (6) is triggered. Wherein, the sound position close to the end (21) means that the distance between the sound position and the end (21) is within 15 centimeters.

Please refer to the second figure, the third figure and the sixth figure. At this time, since the sound position detection module (4) detects that the sound position is close to the end (21), and the contact sensing module (5) and the infrared sensing module (6) are both triggered, the control module (3) will control the glass window (2) to stop closing immediately, so as to prevent the glass window (2) from pinching the user (A). With the three sensing methods, the accuracy of the anti-pinch window can be greatly improved, avoiding misjudgment by a single sensing method due to changes in external environmental factors, and avoiding the trouble that the user needs to constantly re-operate to close the glass window (A) due to misjudgment. In actual implementation, only two of the sensing methods can be combined, for example, the sound position detection module (4) is matched with the contact sensing module (5), or the sound position detection module (4) is matched with the infrared sensing module (6), or even only the sound position detection module (4) is used to detect the sound on the surface of the glass window (2).

Please refer to the first figure, the second figure and the sixth figure. In the embodiment of the present invention, three sensing methods are used. When only the sound position detection module (4) detects the sound position, but one of the contact sensing module (5) and the infrared sensing module (6) is not triggered, the control module (3) will judge that the sound position detection module (4) is a misjudgment, or the sound position detection module (4) does not detect the sound position, but the contact sensing module (5) ) and the infrared sensing module (6) are triggered, the control module (3) will also judge as a misjudgment. For example, when the door panel (1) adjacent to the glass window (2) is knocked, the sound position detection module (4) may misjudge the sound on the glass window (2), but since the contact sensing module (5) and the infrared sensing module (6) are not triggered, the control module (3) will judge that the sound position detection module (4) is a misjudgment. And when the user (A) inside the vehicle is smoking, the smoke may cause the infrared sensing module (6) to be triggered, but at this time the sound position detection module (4) and the contact sensing module (5) are not triggered, so the control module (3) will judge that the infrared sensing module (6) is a misjudgment. And when the user (A) approaches the door panel (1) or the glass window (2) using an electric field, magnetic field, etc., it may affect the sensing of the contact sensing module (5) and cause the contact sensing module (5) to be triggered, but because the user (A) has not touched the glass window (2), the sound position detection module (4) and the infrared sensing module (6) are not triggered, so the control module (3) will judge that the contact sensing module (5) is a misjudgment. It can be seen from the above examples that the present invention can indeed improve the accuracy of the anti-pinch window through the combination of the three sensing methods. However, none of the above scenarios are drawn in the drawings, and are simply explained in words.

Please refer to the third figure, the fourth figure and the seventh figure, also when the glass window (2) is being closed and the end portion (21) is moved towards the abutting edge (12), the following describes the situation where the user (A) touches the glass window (2) away from the end portion (21) with his hand.

Please refer to the third figure, the seventh figure and the eighth figure, when the user (A) puts his hand close to the glass window (2) and touches the glass window (2) away from the end (21), for example, the glass window (2) At the bottom, the sound will also be emitted on the glass window (2). At this time, the sound position detected by the sound position detection module (4) will be far away from the end (21); at the same time, the user (A) will be triggered when the user (A) touches the glass window (2) due to the electric charge on his hand;

Please refer to the second figure, the third figure and the eighth figure. At this time, since the sound position detection module (4) detects that the sound position is far away from the end (21), and the contact sensor module (5) and the infrared sensor module (6) are both triggered, the control module (3) will control the prompt module (7) to send the prompt signal, such as a warning sound effect, or a voice to remind the user (A) to leave the glass window (2), and the glass window (2) will continue to close to the end. The portion (21) is against the abutting edge (12). When the prompting module (7) sends out the prompting signal, in addition to the user (A) who touches the glass window (2) with his hand, other users (A) inside the vehicle can also notice that the user (A) puts his hand on the glass window (2) through the prompting message.

It should be added that the glass window anti-pinch method is used when the glass window (2) is closing, and when the glass window (2) is opening, that is, when the end (21) is moving away from the abutment (12), or when the glass window (2) is not moving, the glass window (2) is unlikely to pinch the user (A), so it is not necessary to use the glass window anti-pinch method to avoid the user (A) being pinched.

Based on the description of the above-mentioned embodiments, the operation, use and the effects of the present invention can be fully understood, but the above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention can not be limited with this, that is, simple equivalent changes and modifications made according to the scope of the patent application for the present invention and the contents of the description of the invention are all within the scope of the present invention.
